Filed: 1990-03-19
Abstract: PURPOSE:To reduce the area of the interface of a depletion-layer end on the (n) layer side with the increase of bias, and to augment a capacitance ratio with the increase of bias by forming the solid shape of the operating layer of an ultra-stepped varactor diode in a shape that the solid shape is narrowed to the inside in the depth direction. CONSTITUTION:A semi-insulator (semi-insulating) S.I. layer 2 is laminated on a high-concentration n-type GaAs substrate 1, and a bowl-like hole in which a bottom as an element section penetrated through the S.I. layer 2 is narrowed is bored through a window bored to an SiO2 film 7 on the S.I. layer 2. n-type epitaxial layers 3 as operating layers are grown selectively in the hole. The conditions of growth are controlled at that time, thus acquiring desired n, n<+> impurity concentration profiles. A p<+> layer is formed through a diffusion or ion implantation, and a p-n junction is formed. A contact 5 as an negative electrode on the p<+> side and a contact 6 as a positive electrode on the n<+> side after the polishing of a rear are shaped through metallizing.
